False.
Artries in general have thicker walls than veins. (thicker tunica media)
This is because artries need to withstand high blood pressure when the heart pumps the oxygenated blood to the rest of the body while veins carry blood (deoxygenated) at lower pressures, hence they are thinner compared to artries
Hope This helps!

Compounds consist of atoms of different elements. In compound the atoms are present in fixed proportion. By changing the proportion compound will changed. For example,
Nitrogen and oxygen reacted to form the compound. By changing the proportion both will form different compound.
NO₂
Nitrogen dioxide consist of one atom of nitrogen and two atoms of oxygen. Their ration is 1 :2
NO
In nitric oxide one atom of oxygen and one atom of nitrogen are present.
Their ratio is 1 : 1.
N₂O
Nitrous oxide consist of two nitrogen atoms and one oxygen. Their ratio is
2 : 1
N₂O₄
Dinitrogen tetroxide consist of two nitrogen atoms and four oxygen atoms. Their ratio will written as 2 : 4
N₂O₅
Dinitrogen pentoxide consist of two nitrogen atoms and five oxygen atoms. Their ratio will written as 2 : 5
<span>Eyes are sensitive to light and when light falls on them, they transmit electrical signals to the brain. The lens in the eye focuses light falling on it, on to the retina. Depeding on the amount of light and distance of objects from the eyes, the lens changes shape to allow focus on objects at varying distances and this is called accommodation.</span>
